Adjustiiieet of the. 'heed 22piovided by its threaded mounting oo the rod 2l. may be mede so tlm-t propel loieeeme on tbe patch may be maintained.

After tbe petali bee'been under peeseie in tlie beeted mold :toiP e suiiioieiit length oi' time tbe level" l? is tbiowo beek to allow tbe spying to lii't' tbe rod end heed eo that the peesei block end eend moy iemoved tbe goetoli telco@ mold.,
